Poly 318

[Anne]

Well thanks for the links.
Basically no further ahead. The left side Exhaust manifold exits at the rear, however there are 3 or more style of exit flanges, and exit curvature so it is important to know what cars they came from. Chrysler produced many different cars with a poly 318 and knowing what manifold went were is important when sourcing one.

The only way you are going to know with absolute certainty is by finding out what casting numbers were used on the Bristol cars. Given that you have a car with the manifolds on, you are in a position to acquire those numbers :-)

Don't see how that casting numbers help or maybe by chance?
I have 2 left manifoldsne is useless as badly broken at the end. The other one I am using but it's cracked...will get it welded this winter.
The numbers are: 2658381 and 22881901. No similarity and even the quantity of numbers is different.
So both numbers would work but that is not the way people in North America work. They would want info such as: 1963 Valiant as in a specific car, and Sandy mentioned Plymouth but there are several versions of Plymouths as in Fury, Belvedere, Valiant and Barracuda...maybe others. Knowing which one is the information I need or for that matter many of us do.

The reason they can be helpful (in my view) is because many of the cars that used them used several different casting numbers over the production period. So if you can identify a car that used a particular casting number, and a 313/318 engine, then it may be possible to identify other casting numbers that will fit.

The fact that you have two different casting numbers that fit your car, demonstrates this.

I have been doing a little research into this and discovered that the part numbers on the Bristol Cars parts list for the 409 may in fact be casting numbers - I had assumed they were internal Bristol part numbers which are usually meaningless outside the company.

The parts list says as follows;

Part No. 2129196 Exhaust Manifold R.T. Type 408/MII (1)
Part No. 2465879 Exhaust Manifold R.T. Type 409 & 410 (1)
Part No. 2268128 Exhaust Manifold L.T. 2206274

The book ULTIMATE AMERICAN V-8 ENGINE DATA BOOK 1949-1974 BY PETER C. SESSLER (2nd Edition) it lists 2268127 as being a left manifold used on Dodge cars (Dart, Polara, Coronet) with 318 Poly engine between 1962 - 1965. That's just 1 digit different from the LT manifold in the Bristol parts list 2268128 .

It also lists 2129194 as the RH manifold for Dodge 318 Poly engines in 1962 (again only one digit different from the Bristol parts list 2129196)

Anne, I wonder if the manifolds fitted to your car are not the originals, and the reason they have broken is because they were not the right ones and didn't quite fit correctly with the rest of the system or the body.

Well none of those numbers tie in with mine. In addition on this Forum there is a picture of a broken manifold with the numbers 2206275 clearly marked and again different from your numbers.
My exhaust lasted the car's life until an unfortunate truck driver broke them when unloading the car. The pipes under the car are in alignment with the manifold so I have no reason to question their correctness. In any case even if the LH was not correct it still proves there are many casting numbers.
Other manifolds of Chrysler engines of the period will not clear the frame.
Have tried to attach a picture but no luck.
As already mentioned there are 3 or more manifolds for the 318 depending on car/truck model so the ULTIMATE AMERICAN....book is in error with only one casting number, given I have just shown you 3 ! Perhaps they got their info from Sethright LOL So 3 numbers of mine + one from ULTIMATE AMERICAN makes 4.. But wait..on E Bay http://www.ebay.com/itm/1962-63-64-6.../201676760124?
there is one for sale now today with number 2288186 clearly listed for a poly LH side, so there are at least 5. Proves my point that the casting numbers are meaningless. What would have meaning is what car was our engine sourced from or what LH exhaust did they use?

Your derision is misplaced (and uncalled for). Who said the ULTIMATE AMERICAN book lists only one casting number for this exhaust manifold? It lists others, I just didn't transcribe them all!

Well let us know when you find out. LOL

[Anne]

Ok..the clear impression was there was only one.
Given that now you tell me that the ULTIMATE book has more than one LH casting number how many are listed?
Are there any that match the ones I have provided? What I have shown, is that based on my limited knowledge, at this point there are 6 or more LH casting numbers...possibly more? This is why I find casting numbers a curiosity but not of much help in sourcing a manifold.
